SAFETY RAZOR WITH CONTINUOUS BLADE Filed Apr11 5, 1934 Pmnaa Aug. 21,1935 Eivind Jensen Eckbo, Oslo, Norway Application April 5, 1934, SerialNo. 719,203 In Norway ADI-ll 11, 1933 2 Claims.

The present invention has for its object a safety razor of the kindwhich comprises a continuous blade in the form of a thin ribbon ofsteel, which is adapted to be wound from one spool to another across aguiding member serving as the usual guard for the sharpened edges of theblade-during use.

The safety razor in accordance with the present invention comprises anoblong frame, which is provided at one end with a closed circular boxfor receiving a, spirally wound new razor blade rib-- bon. The ribbon isadapted to be pulled out through a slot in the side wall of the box andfrom there passes over the guard or working member to a receiving reelprovided with a suitable handle in order to be rotated for winding theused parts ribbon blade onto the same. The said reel may also be placedin a closed box similar to the one used for the new part of the ribbon,although this is not absolutely necessary.

The closed box or receptacle for the new continuous steel ribbon may befilled with'vaseline or other lubricating material in order to preventcorrosion.

Intermediate the two spools for the new and used part of the steelribbon the frame is provided with a working part or guard, which isadapted to be moved perpendicularly on the line connecting the two spoolaxes and which is adapted to be pressed against the lower side of theribbon blade, being provided with the usual guard members on both sides.

n the top of the ribbon blade there extends between the two spools alongitudinal ribbon,

which is securely connected with the frame and the part of whichimmediately above the adJustable guard is somewhat narrower than theblade, so that the edge of the blade projects a suitable distance on oneor both sides of the same.

0n the drawing a preferred form of the invention is illustrated.

Figure 1 is a side view, Figure 2 is a cross section on the line IIH onFigure 1, Figure 3 is a sectcn on the line lIIlIl on Figure 1 andFigbilled-i shows a part of a preferred form of ribbon The safety razorcomprises a frame I, which may take the form of a disc, having an edgeflange 2 giving the frame the form of a flat box, which may preferablybe adapted to be covered by means of a disc 3, although this is notabsolutelv necessary.

Near one end of frame I there is located a discshaped receptacle 4,which may be provided with a particular cover or may be adapted to beclosed by means of the previously mentioned covering disc 3 when thelatter is put in position.

The receptacle 4 is provided in its side wall with a slot 5, throughwhich the spirally wound ribbon blade 6 may be pulled out. The spirally'wound spool 6 lies loose in receptacle 4 and the latter as previouslymentioned may be filled with Vaseline or other lubricating material inorder to prevent corrosion.

Near the other end of frame I there is located 10 a receiving reel I,the shaft of which is provided with an exterior handle or knob 8. Thefront end of the razor blade ribbon is secured to reel I in somesuitable manner and is wound onto said reel by turning handle 8, whichmay be associated with a suitable ratchet or the like.

Between the two spools blade 8 passes below a rib 9, which is secured toor integral with frame I or the edge flange 2 thereof. Below blade 8there is located a clamping disc or guard member III, which is-securedto a rod II adapted to be longitudinally displaced in the guide I2 bymeans of screw I3 in order that the clamping disc. Iii may clamp therazor blade against the ribbon 9 during the use of the razor. Clampingdisc II) has a straight middle part, but is somewhat curved near bothends, whereby the razor blade is caused to take a slightly curved shape,which may be an advantage in order to better reach the various parts ofthe face.

Along one or both sides the clamping disc is' provided in the usualmanner with guard teeth I4 or the like. v

In the form illustrated on the drawing the blade is provided with edgeson both sides, but the 5. blade 2 may also be formed with edge on oneside only, in which case the rib 9 may consist of a part of the flange 2and be integral with or directly secured to disc I on the side at whichthe blade has no edge.

In order to protect the edge of the blade the same as illustrated onFig. 4 may be provided with small projections I 5 separating the partsI6 which are provided with razor edge on one or both sides.

What is claimed is:

1. A safety razor, comprising an oblong flat frame having a ribextending transversely across approximately the middle of onelongitudinal side thereof, a spool in each longitudinal end of the 50frame, a continuous ribbon-shaped razor blade mounted on and extending.between said spools,

. one spool containing the fresh blade portion and the rib and betweensaid spools, and adapted to be displaced transversely of the major axisof the irame, to clamp the blade into shaving position against said rib.A

2. A safety razor, comprising an oblong flat frame having a ribextending transversely across approximately the middle 0! onelongitudinal side thereof, a spool in each longitudinal end of theframe, a continuous ribbon-shaped razor blade 10 mounted on andextending between said spools,

atlases one spool containing the fres h blade portion and the other theused portion of the ribbon, said razor blade being provided withlaterally extending projections separating the sharpened edge parts ofthe blade, and a clamping and guard member in said frame between saidspools, and adapted to be displaced transversely of the major axis ofthe frame, to clamp the blade into shaving position against said rib.
